I’m trying to start from absolute basics. I have ruby 1.8 installed
and working and want to have a look at the Tk interface.
I get the following:-
irb(main):001:0> require ‘tk’
RuntimeError: tcltklib: fail to Tk_Init(). this isn’t a Tk
applicationunknown color name “Black”
from /usr/lib/ruby/1.8/tk.rb:1102:in `initialize’
Any ideas please?
